What flash notifications are and where to find the setting

Flash notifications are the bright LED flashes your iPhone sends when you get a call, text, or other alert — a visual signal instead of sound. If you have an iPhone 11 or newer, you'll find this setting in the Accessibility menu, not in the main notifications area. Older iPhones (iPhone XS and earlier) don't have this feature built in, though some accessibility apps can mimic it.

The flash notification feature was designed for people who are deaf or hard of hearing, or who need a visual alert when their phone is on silent. It's separate from your regular notification sounds and badges, so turning it off won't affect those settings.

Key Takeaways

  • Flash notifications are LED flashes that alert you to incoming calls and messages, found in Settings > Accessibility > Audio/Visual on iPhone 11 and newer.
  • You can turn off flash notifications entirely, or keep them on but disable them for specific apps.
  • Turning off flash notifications does not affect your notification sounds, badges, or vibration patterns.
  • If you have an older iPhone, this feature is not available in standard settings, though some third-party apps offer similar functionality.

Steps to turn off flash notifications on iPhone 11 and newer

Open the Settings app and tap Accessibility. Scroll down and select Audio/Visual. You'll see a toggle for LED Flash for Alerts — tap it to turn the feature off. That's the complete setting for most users.

If you want to keep flash notifications on but disable them for specific apps, stay in the Audio/Visual menu. Below the main toggle, you'll see a list of apps that can trigger flash alerts. Tap the minus sign next to any app name to remove it from the flash notification list, or tap the app name itself to see more options for that app.

After you make changes, close Settings. The new setting takes effect immediately — you don't need to restart your phone.

What happens when you turn off flash notifications

Turning off the LED Flash for Alerts toggle disables all visual flashing for incoming calls, messages, and app notifications. Your phone will still vibrate and play notification sounds as normal, and your notification badges (the red circles with numbers) will still appear on your app icons.

If you use Do Not Disturb or Silent mode, flash notifications won't work during those times anyway — the feature only activates when your phone is in regular mode. Some users keep flash notifications on specifically because they work even when the phone is face-down on a table.

Turning flash notifications back on if you change your mind

Go back to Settings > Accessibility > Audio/Visual and toggle LED Flash for Alerts back on. If you had disabled it for specific apps, you'll need to add those apps back to the list by tapping the plus sign next to their names.

You can also control which apps trigger flash alerts without turning the feature off entirely. In the same Audio/Visual menu, you can toggle individual apps on or off, so your phone might flash for calls and texts but not for email or social media notifications.

Why your iPhone might not have this setting

If you have an iPhone XS, XS Max, XR, or older, the LED Flash for Alerts setting doesn't exist in Accessibility. Apple added this feature starting with iPhone 11. If you're using one of these older models and want a visual alert for notifications, you'll need to look at third-party apps from the App Store that offer similar functionality, though they work differently than the built-in feature.

Check your iPhone model by going to Settings > General > About and looking at the Model line. If it says anything other than iPhone 11 or later, the native flash notification setting won't be available to you.

Other notification settings that work alongside flash alerts

Flash notifications are just one part of how your iPhone alerts you. You can also control notification sounds, vibration patterns, and whether badges appear on app icons. These settings live in Settings > Notifications, where you can customize alerts for each app individually.

If you want your phone to be completely silent and dark, you can use Focus modes (Settings > Focus) to mute everything including flash alerts. Focus modes let you create custom profiles — like "Work" or "Sleep" — that turn off specific notifications during certain times or when you're in certain locations.

Frequently Asked Questions

Will turning off flash notifications affect my alarm or timer?

No. Flash notifications only control alerts for calls, messages, and app notifications. Your alarms and timers will still work normally and will alert you with sound and vibration as usual.

Can I make flash notifications work only for phone calls, not texts?

Yes. In Settings > Accessibility > Audio/Visual, you can toggle individual apps on and off. Disable the Messages app to stop flashing for texts while keeping it on for Phone calls.

Does flash notification drain my battery?

Not noticeably. The LED flash uses very little power. Turning it off won't make a meaningful difference to your battery life.

What if my flash notifications stopped working even though the setting is on?

Make sure your phone is in regular mode, not Silent or Do Not Disturb. Also check that the specific app is enabled in the Audio/Visual menu. If it's still not working, restart your phone by powering it off and back on.
